Directions

Mix graham crackers and 5 teaspoons butter together in a bowl until mixture is dense and moldable. Press graham cracker into the bottom of the prepared tins to form the crusts.

Combine chocolate chips and heavy cream in a pot over medium-low heat. Cook and stir until chocolate chips are melted, about 3 minutes. Pour mixture evenly over the crusts; top each tart with 4 marshmallows.

Bake in the preheated oven until marshmallows are golden brown, about 2 minutes.
